It will find the response time to resolve the DNS name cow.ciscoexam.online. Domain Name System (DNS) response time is computed by calculating the difference between the time taken to send a DNS request and the time a reply is received. The Cisco IOS IP SLAs DNS operation queries for an IP address if the user specifies a hostname, or queries for a hostname if the user specifies an IP address.
It will not find the response time to connect to the DNS server at 10.52.128.30. That is the IP address of the DNS server being used for the operation (10.52.128.30). However, it will measure the response time to resolve the DNS name cow.ciscoexam.online.
It will not start in one minute. It will start immediately, as indicated by the start-time now parameter.
It will not gather data for one minute. The numeral 1 in the first line refers to the IP SLA number, and the numeral 1 in the last line refers to the IP SLA number to be scheduled.
